Human Factors of Safety Assessment

Human error is a common cause of major incidents. People are often relied on to recognise and control incidents, acting quickly and effectively to minimise the effects of an escalating accident.

Safety case regulations require that a systematic approach is required to foresee and understand all significant human errors and to identify Human Factors risk reduction options throughout the life cycle of design, operation and decommissioning. Claims on human performance must be realistic and validated. Human Factors risk controls must be effective and meet recognised good or best practice.

A good safety management system incorporates Human Factors throughout its evolvement to deliver comprehensive and effective risk controls that are taken on board by end users.

Industries without a regulatory requirement recognise that implementing best practice safety assessments results in a better managed, safer and more effective organisation.

The training, staffing levels, human machine interface, procedures, workload management, workspace design and other Human Factors requirements for safe operation must be identified and integrated into operational safety management systems.

Human Factors of Safety Assessment

It is recognised good practice to develop and implement a Human Factors integration plan for safety assessment and assurance of all high hazard and safety critical systems.

Human Factors of safety assessments ensures

  • Systematic and complete identification of human errors
  • Understanding of the cause and effect of human errors
  • Human failures and human based safety claims are screened for further analysis
  • Valid and realistic estimates of human error likelihood
  • No over-reliance on human based safety claims
  • Valid assumptions about human performance
  • Human Factors risk controls help reduce risk As Low As Reasonable Practicable
  • Human Factors requirements are integrated into operational safety management

Supporting high human performance for safety critical tasks

 

Assuring regulatory approval of safety cases

Our Services

We provide the full range of Human Factors assessment services in support of Safety Cases, COMAH, Safety Assessment and Verification. We also act as Independent Technical Assessors and Peer Reviewers of the Human Factors aspects of safety cases and safety assessments. This includes the Human Factors of:

  • What if, HAZOP, FMEA and HAZAN
  • Deterministic, Probabilistic and Quantitative Risk Assessment
  • Bow ties, Fault and Event Trees
  • Hazard Identification
  • Design Substantiation
  • Optioneering reviews
  • ALARP

We support numerous safety cases and assessments of complex safety critical systems, including:

  • Early System Designs
